Thanks for your reply.  I introduced the quoting mistake when I was  
writing the email - unfortunately that isn't the actual problem.  It looks  
like the problem is a fault with the Math.round() function on the  
implementation of Java 1.2.2 I'm working on.

I've downloaded the Xalan source, so I'm just going to try patching in a  
call to Math.trunc() instead and see if that solves the problem.

Cheers,

Stuart.
